As you get older, there are going to be a few more challenges, but thankfully I'm still feeling good.

What's really heavy on my heart is fighting physical inactivity.

I love the relays. Track is such an individual sport, so it's fun to do something together.

My dad's a pastor and a seminary professor, my mom, she has such great faith.

I spend around two and half hours on the track every day running and another 2 hours in the weight room lifting weights with my strength coach.

The pressure is hard. You get - the world is only watching every four years, and I think lots of people feel like they have to win in that time frame.

I've heard so many stories of young girls watching the Olympics and being inspired by it, and they want to do it now, and that's really cool.
